Fair Representation of Financial Statements

Fair Representation of m iodintary Statements1. INTRODUCTIONThe Financial account Standards Board was formed to resolve the problems faced by the external pecuniary reporting regiment. In particular, it hopes to promote the archetypeization of international bill tireds through its International Accounting Standards (IASs) to facilitate transactions and improve pecuniary markets. Underscoring the FRSBs philosophy is to enable the whiteish presentation of pecuniary literary arguments. This report discusses this innovation and evaluates whether the application of a standardized invoice reporting regiment would reach its accusatorys with a critical examination of virtu every(prenominal)y score standards.2. FAIR demonstration DEFINEDWhenever we mention the fair presentation of financial contestations, we ar referring to the history concept of authoritative and fair piece of taildidate. The phrase dead on target and fair in an report context does not have the aforesaid(prenominal) meaning as true and fair in a general context. Thus, true in an account statement context does not mean in accordance with the facts or not false and fair in an report context does not mean just or unbiased.The close to generally true version of true and fair in an be context is that accounts be true and fair if they atomic number 18 prep ard and presented in accordance with generally accepted business relationship principles. Thus courts have held that accounts base on historical salute present a true and fair view. Riley has pointed out that the various Companies Acts assume the presentation of a true and fair view and not the true and fair view. The implication is that in a particular circumstance no single view is true and fair besides that there atomic number 18 several views each of which is true and fair. Presumably, any generally accepted accounting system provides a true and fair view. on that point be some who argue that different ac counting standards does not inhibit the adoption of fair presentation while some others believe that a uniform international standard like IAS is the outdo means of achieving fair presentation of financial statements.3. THE pillow slip FOR DIFFERENT ACCOUNTING STANDARDS3.1 Diversity is DesirableIt has been argued by some that a range of accounting methods is desirable because of the diverse circumstances of different businesses. In some circumstances one method would be desirable and in other circumstances some other method would be some appropriate. Diverse accounting methods are necessary because of diverse circumstances. For example, it could be argued that when a non-controlling interest in another(prenominal) company is acquired and where there is a veritable influence over its policies, the equity method would reflect the circumstances more(prenominal) accurately than simply showing the investment at cost.Given a variety of accounting methods, it is argued that managemen t should choose the one which best reflects the comical circumstances of the situation. The ability to choose the most appropriate method should lapse to comparability of accounting reports. More meaningful comparisons would be possible because accounting reports reflect the circumstances in each case. The independent auditor should crack that management selects the most appropriate method for the presentation of a true and fair view. If management does not choose the best method, the auditor impart not confirm the presentation of a true and fair view and a qualified audit report should result.3.2 Arguments Against International Financial Reporting StandardsJust as there are many compelling arguments in favour of IAS, there are to a fault every bit compelling arguments against it. sensation of the major criticisms against IFRS is that poorly developed and developing countries view it as a form of imposition of rules or neo-colonization by economically superior countries (Mednic k, 1991). Secondly, normalization goes against the inherently flexible nature of accounting. One of the key principles of accounting is content over form, so providing international standards would be contrary to this. When accounting rules are standardized or harmonized, they cannot possibly be flexible enough to tally into the enormous scope of different national situations, legal systems, stages of economic ingathering and cultural differences. Instead of aiding progress, such rigid and inflexible standards whitethorn actually hinder it.Next, some experts argue that it will be very demanding for international accounting standards bodies like the IASB to reach a universal consensus on some issues. As a result, concessions and compromises will have to be make so that it becomes satisfying to the international community (Berton, 2000). When this happens, the standards become inadequate and permissive. other argument against international accounting standards is that it could be dangerous as the standards may erode scratch and cause volatility in the balance sheets of the companies (Parker, 2002). As a result, companies need to educate their investors about the effects of international accounting standards on the account profits and liabilities.Finally, some have expressed commercial enterprise that international standardization or harmonization may cause standard overload. Companies that have to deal with social, political, national and economic pressure will be overextended to comply with the more complex and expensive international collectments. This may add to operating costs.4. THE CASE FOR INTERNATIONAL FINANCIAL REPORTING STANDARDS4.1 Problems with DiversityThere is the availableness of a wide choice of accounting methods. For many transactions, accountants are able to choose from a selection of accounting methods each of which is equally acceptable and which often give widely different results. However, there are two main types of criticism leveled against this kind of regeneration.One, it is suggested that the availability of several acceptable alternative accounting methods for a single transaction could make the accounting reports of different companies non-corresponding. Differences in reported results could reflect different accounting procedures sort of than different doings. For example, suppose that Company A expensed all research and learning expenditure, use FIFO for inventory and depreciated its assets on a straight-line basis. Any differences in the reported profits and balance sheets of the two companies would be due, at least in part, to differences in accounting procedures and any assessment of relative performance and financial position would be difficult to make. The critics argue that diversity in accounting methods reduce the utility of accounting reports by measuring incarnate performance in different ports.Two, it is also suggested that the availability of different accounting methods allows management to choose those methods which give the desired result. In other words, profits could be manipulated by the choice of accounting method. If management wants lower profits, conservative accounting procedures could be use. Choosing accounting procedures to satisfy management objectives is sometimes set forth as creative accounting. In America, researchers have found substantial endorse of creative accounting. The critics regard creative accounting as particularly naughtily and finish that financial statements cannot be used with any confidence to sum of money or equation managerial performance.The common element of these two criticisms is that the availability of a choice of accounting methods places to a lack of comparability in accounting reports.4.2 profit DisclosureThe second argument for IAS is to seek increase revealing. Two types of increase revealing are suggested. One, it is argued that the problems of diversity could be at least partially overcome by deta iled disclosure of accounting method. Under this proposal, accounting reports would include a statement of the methods used to work depreciation, unearned income, inventory and so on. It is suggested that this additional selective data would enable statement users to recast the accounting reports into a form suitable for comparison with the reports of other years or other companies.Two, it is suggested that where an accounting method is different from that used in the previous report, the fact of the trade of method and the effect of the change on reported profits or balance sheet items should twain be disclosed. With this additional information statement users would be able to echo the accounting reports of a company to make them comparable on an image basis. The effect of creative accounting would be disclosed.It should be noted that the increased disclosure response leaves companies and their auditors with a choice from a range of accounting methods. Diversity in accountin g method is not reduced. The increased disclosure allows statement users to make accounting reports comparable by recasting them in the form they need.Increased disclosure is a solution to the problem of diversity can be criticized on the grounds that the benefits may not be shared equally by all statement users. It requires a statement user with accounting skills to recast financial reports on a comparable basis. Statement users without access to these skills would receive no benefits from these additional disclosures. Indeed, they may be worse off as sophisticated statement users recast the financial reports and to make better decisions. Any solution to the diversity problem which places the one on statement users and which could therefore discriminates against a group of users is clearly unsatisfactory.4.3 Increased UniformityIt is also widely believed that a universal adoption of IAS would conduct to uniformity of financial statements internationally. When different standards a re used, it is sometimes difficult to compare the financial performance of two companies. Comparability would eliminate misunderstandings about the dependability of foreign financial statements and would remove one of the most in-chief(postnominal) impediments to the guide of international investment. Narrowing the range of choice of accounting methods is usually exposit as increasing uniformity. In most cases, increased uniformity is achieved by issuing statements of accounting principles or standards which specify the accounting method for a particular transaction or event.Increased uniformity means that the uniform accounting methods are likely to be used in the same circumstances by different companies and at different times. The onus is on management and accountants rather than statement users. There are several arguments used to support the case for greater uniformity of accounting method. Firstly, the most primary(prenominal) argument is that uniformity of accounting pr ocedures will allow comparisons of accounting reports. like situations will be reported in a similar way and results will be directly comparable. Any difference in reported results will be due to differences in the circumstances and not in the accounting method.Secondly, many accountants believe that increased uniformity would make their jobs very much easier. Choosing an accounting procedure is for many accountants time consuming and difficult. It may lead to conflict between management which wants creative accounting and accountants who believe that another method is more appropriate. With uniformity, the chance of conflict over accounting method would be reduced.Thirdly, with uniformity, accountants would be better able to defend their procedures in court. Because their choices would be limited, they could not be accused or choosing an accounting method to equate the needs of any particular group. This in an all important(predicate) consideration for accountants.4.4 toll Ben efitsThere are numerous financial benefits of having IAS. The initial is that it decreases the cost of data collection (Choi et al, 1999). Time and money will be saved on consolidating divergent financial information when more than one set of reports is necessitate to comply with the different national laws or practice. Secondly, it is believed that the ease of comparison of information and the reduced cost of collecting data will help spur the knowledge of capital markets through the inflow of foreign capital (Don and Thomas, 1995). Investors, financial analysts and foreign leaders will be able to understand the financial statements of foreign companies and they would be able to compare the investment opportunities that will encourage them to make the correct investment decision. This in turn will also facilitate the movement of funds. As taxes are levied on the total income of a business, it would be of great help to national tax authorities around the world if net income was calculated on similar accounting principles and practices. In addition, this will provide firms with a competitive advantage. International accounting and disclosure standards would make it easier to conduct the competitive and operational analyses needed to run a business. It will also become easier for top management to manage important relationship with stakeholders such as guests and suppliers. Multinational corporations will benefit the most and it will also become easier for them to fulfil the disclosure requirements for international stock-taking exchanges. Finally, harmonization of accounting standards will decrease audit costs and increase the efficiency of the audit (Choi et al, 1999).5. DIFFERENCES IN ACCOUNTING TREATMENTTo better understand how universal adoption of IAS would eliminate differences in accounting treatment, let us consider some examples of divergent accounting treatment. For this purpose, a comparison is do between IASs and the United States Generally Accepted Accounting Principles (US-GAAP).5.1 Changes in wear and tear or Amortization MethodAccording to IAS 16 and IAS 38, there is an intelligible stipulation that changes in depreciation or amortization method must(prenominal) be accounted for as a change in estimate. However, US-GAAP treats these changes as changes in policy by demonstrating the cumulative effect of the change in the income statement. These require retrospective changes, which are not required by IAS.5.2 Impairment of AssetsIAS 36 uses a discounted impairment bring out, because the value in use is by commentary a discounted value. Reversal of impairment losses recognized in front years is allowed. On the other hand, in the US-GAAP, if the sum of the expected funds flows is less than the carrying measure of the asset, the entity shall recognize an impairment loss. This means that the impairment trigger is an undiscounted amount. Reversal of previously recognized impairment losses is prohibited for assets to be held and used.5.3 Impairment of GoodwillAccording to IAS, the recoverable amount of a bills generating unit should be compared with the carrying value of its net assets. Resulting impairment losses should first be deducted from goodwill and then from other assets on a pro-rata basis. However, US-GAAP requires end of the implied fair value of the goodwill. If the implied fair value is less than its carrying value, this carrying amount should be reduced. Such a goodwill impairment test cannot affect the carrying set of other assets.5.4 Business Combinations in-process Research and DevelopmentFor IAS, purchased in-process research and development that meets the light criteria for an intangible asset should be valued at fair value. make up if it is not a separate identifiable intangible asset, the IAS method results in capitalization of those costs as part of goodwill. Under US-GAAP, purchased in-process research and development assets both tangible and intangible should be c harged to expense at acquisition date if no alternative future use for the assets can be determined.6. INCONSISTENCIES IN IASAlthough IASs are deemed to improve fair reporting, there are occasional inconsistencies that often hamper their effectiveness. Indeed, the IASB has tried to correct some of these inconsistencies, but there are sleek over flaws in the overall framework. The following are some of the inconsistencies that have been corrected in recent years.6.1 Classification of tonnage duty Taxes in IAS 112In some countries, shipping companies are allowed to choose to be taxed on the basis of tonnage transported, tonnage capacity or a notional profit sort of of the standard corporate income tax regulations. In the past, tonnage capacity was regarded as a basis for dutiable income. This is based on a flawed assumption. Income taxes are calculated on taxable profit which implies net, rather than gross amount. Taxes either on tonnage transported or tonnage capacity are based o n gross instead of net amount. Therefore, such taxes would not be considered income taxes and would not be presented as part of tax expenses in the statement of comprehensive income.6.2 Accounting for gross revenue Cost in IAS 38Some problems arise among real the three estates developers. IAS 2 does not permit selling costs to be capitalized as inventory if the real estate units are considered to be inventory. However, other standards conclude that some direct and incremental costs recoverable as a result of securing a specifically identifiable contract with a customer may be capitalized in narrow circumstances, for example in IAS 11 (Paragraph 21) and IAS 18 (Appendix 14(b)(iii)). Hence, it is not possible to reach a conclusion on the appropriate accounting for board categories of selling and marketing costs in all circumstances.6.3 Disclosure of Idle Assets and Construction in Progress in IAS 16In accordance with paragraph 74(b) of IAS 16, an entity is required to disclose the am ount of expenditures recognized in the carrying amount of an item of property, plant and equipment in the charge of its construction. Paragraph 79(a) encourages an entity to disclose the amount of property, plant and equipment that is temporarily idle. Paragraph 112(c) of IAS 1 requires an entity to provide in the notes information that is not presented elsewhere in the financial statements that is applicable to their understanding. The disclosure regarding idle assets might be particularly relevant in the current economic environment. Therefore, IASB should review all disclosures encouraged with the objective of either confirming that they are required or eliminating them.7. CONCLUSIONTo end, all accountants agree that the fair presentation of accounting and financial statements is important. However, what exactly constitutes fair presentation is a contentious and debatable matter. Some insist that adopting IFRS is the best way of achieving this objective while others assert that substance is more important than form and that it is perfectly acceptable to use different accounting standards so long as it shows some form of fair presentation. While I personally believe that it would be ultimately benefit the international financial community to have one standard to prevent confusion, its implementation is still some years away.

Dayan During His Military Career History Essay1. Moshe Dayan was a known Israeli force elevator car draw and politician.

In 1958, Moshe Dayan retired from the Army.WITH BRITISH ARMY14. During his tenure with British army, he served with the forces that liberated Lebanon and Syria from Vichy France during World War II. He practiced the start he gains from the agone especially the guerrilla tactics.

Six died and 21 were wounded on the Israeli side. The high casualty rate was caused by confusion all over which Dayans troops were. The IDF was led by an armored car seized from the Arab Legion. Residents may be in possession of believed the Arab Legion had arrived, completely to encounter Dayans forces shooting at everything as they ran from their homes. Dayan shows his leading qualities of resolution and initiative during this campaign.CEASEFIRE TALKS WITH JORDAN17. In 1949, he participated in ceasefire duologue with Jordanian officials at Rhodes. Dayan served on a commission he ld in Rhodes which had assembled to try to work out a settlement between the Jewish and the Arabs. between 1949 and 1950, he held secret trounces with King Abdullah of Jordan.

Raising the Intelligence and Training Branches of the Israeli Army.b. Surrendering the activities of stores and procurement to the civilian Ministry of Defense.c. Revamping the militarization scheme and ensuring earmark ing for adequate equipment.d. Starting a military academy for officers of the rank of major and above.e. Emphasized strike forces (Air Force, Armour) and on training of Commando battalions.f. authentic a youth wing for military training.19. This is where he highlighted his great qualities of leadinghip of sound knowledge, planning capability and organizing ability.SINAI CAMPAIGN20. Israeli wholes parachuted into the eastern approaches of the Mitla drag near the Suez Canal on 29 October 1956. It was a political verifiable quite a than tactical or strategic objective. The action provided the pretext for a French and British ultimatum to Israel and Egypt, calling on both sides to cease hostilities and run from the Canal area. For diversionary reasons, Israeli forces also advanced on southern and central axes.21. The following day, October 30, Britain and France issued the planned ultimatum, but to no effect, as fleshy fighting between Egyptian and Israeli units persisted. In a s wift, wholesale operation of 100 hours, under the leaders of then Chief of the General Staff, Moshe Dayan, the entire Sinai peninsula fell into Israeli hands, at a cost of 231 soldiers killed. In this stage he practiced his initiative very much more schoolwide manner as a real leader who took conclusiveness past where opponent neer had a jeopardize to reflect.22. In Israel and around the solid ground, the Black Eye Patched General became the symbol of Jewish military proficiency. As a custom, Dayan disliked on anything not directly related to fighting readiness. He emphasized weapons marksmanship, advantages of use of terrain, and an overall aggressiveness.POLITICAL CAREER23. The macrocosm of governing and government was not strange to Moshe Dayan because as chief of round he carried parliamentary responsibilities for conduct of military affairs in boastfully capacity. At the end of his term as chief of staff he shed off uniform and joined at the Hebrew university of Jeru salem as a student in the political science power for period of two year. It was helped him to make better putation to approach political field in gross(a) way. With that foundation he joined Israels labor party and elect and joined as a prestigiousness member of Knesset (parliament) for Mapai area on 3 November 1959.AS AGRICULTURAL rector24. Dayan was appointed as minister of culture in the government of David Ben Gurion from 1959 unit 1964. This subject was not new field to him because he born and brought up in a farming atmosphere field. The orchard, the cowshed, the season of planting and growth were deeply infused in his blood more than tanks, guns and fighting. With his inherent experience he was able to identify problems which were faced in the agriculture field. He found that farmers faced financial difficulties and technical problems due to low prices for products, high yield cost and financial difficulties to buy new tool and machineries. He analysed and place agr iculture systems of other counties. By analyzing, he was able to ease up a planning authority, production and marketing council for each branch of agriculture. He do regional offices throughout the rustic where local farmers could receive agriculture focal point and services.AS MINISTER OF DEFENCE25. Dayans reputation as an effective leader grew when he was appointed Minister of Defense under Levi Eshkol just in time for the Six-Day War in 1967 against Egypt, Jordan and Syria. During Yom Kippur war his actions was critically condemned by province of Israel due to huge frailer of Israel military force. The nations lack of preparation was blamed on Defense Minister Dayan and an outraged public demanded his fortitude. This was caused him to give resignation to Meir in 1974 and he left his appointment.SIX DAY WAR IN 196726. The Six-Day War was initiated byGeneral Moshe Dayan as the Israelis Defence Minister. Although General Dayan did not crawfish part in most of the planning be fore the Six-Day War of June 1967, his appointment contributed to the Israeli success. When the Syrians were shelling Israeli villages in Upper Galilee, Dayan was the one who make the decision to launch a full-scale attack against the Syrians. Rather than delay to be attacked, the Israelis launched a hugely no-hit military campaign against its perceived enemies. The air forces of Egypt, Jordan, Syria and Iraq were all destroyed in fifth June. By ordinal of June, many Egyptian tanks had been destroyed in the Sinai Desert and Israeli forces reached the Suez Canal. On the same day, the whole of the west bank of the Jordan River had been cleared of Jordanian forces. The Golan senior high were captured from Syria and Israeli forces moved 30 miles into Syria itself.YOM KIPPUR WAR 197327. Egyptian President Anwar Sadat launched a force attack against Israel. On Yom Kippur, October 6, 1973, Egyptian armies crossed the Suez Canal, moved anti-aircraft missiles into the supply area, and waged war on Israel. Israeli losses were high and Israel had too laconic a supply of equipment to conduct a prolonged war.28. On October 22, a cease-fire was declared, but the Israeli publics confidence had been severely shaken. Israel had been unprepared for the surprise attack and unable to repulse it quickly. The president of the Supreme Court set up a commission to investigate the performance of generals during the war. The commission recommended the resignation of the Chief of Staff, but reserved judgment on Dayan. The press and the public, however, condemned him. After attending a military funeral at which bereaved parents had called him a receiver of their sons, Dayan submitted his resignation to Meir in 1974.AS FOREIGN MINISTER29. Year 1977, impertinently elected Prime Minister Menachem cast down gave him a second chance by offering him the post of Minister of Foreign Affairs. Although Dayan was from the opposition wear upon Party, he accepted the appointment because he believed,I could significantly crop Israels moves towards achieving a peace arrangement with our nigh Arab States and with the Palestinian inhabitants of Judea, Samaria and Gaza Strip.30. In May 1977, Dayan began negotiating with the Egyptians. As lead negotiator, Dayan began with the premise of receiving an Arab acceptance of Israeli mold over Judea, Samaria and Gaza, in exchange for a return of Sinai to Egypt. He negotiated for 18 months, and held secret meetings with officials in India, Iran, England and Morocco.31. With help from U.S. president and mediator Jimmy Carter, Dayan met with the Egyptians first at Leeds Castle and later at Camp David. Eventually, a peace agreement, the Camp David Accords, was drawn up and signed at 11 p.m. on Sunday September 17, 197832. In 1979, Dayan resigned as Foreign Minister. Dayan and Begin disagreed or so the building of settlements in the territories and Dayan was frustrated by the fact that he was not leading the autonomy talks with the Palestinians. Dayan also felt that he was increasingly being bypassed on foreign policy issues. In 1981, he formed the Telem party, which advocated unilateral disengagement from the territories occupied in 1967. The party received only two mandates in the subsequent elections. loss leaderSHIP QUALITIESINITIATIVE33. Six day war against Egypt, Jordan and Syria is shows Moshe Dayans initiative significantly. When Syrians were shelling Israeli villages Dayan took the initiative to launch a full scale attack against Syrians. He was able to make it triple-crown within very short time, giving deterrence to the Arab countries. It had highlighted the Moshe Dayans initiative and decision taking ability as an effective military leader.KNOWLEDGE34. Moshe Dayan was a commander who had a fantastic knowledge roughly own and enemy. He had studied science at the Hebrew University in Jerusalem. He feature perfect knowledge on his job all the time. Almost at a time the independence of Israel, the new state was attacked by a coalition of next Arab states. Dayan put into practice his knowledge and what he had learnt fighting in World War II.36. As Minister of Agriculture, he toured with the same zeal that he had as Defence Minister, resorting more to seeing to the implementation of his instruction quite a than being confined to an office. Though the Prime Minister and the Cabinet were not too keen on using the expertise of Dayan, they were however hale by the mass to emplace him as the Defence Minister, due to his coarse knowledge on the subject.37. Dayan was an asset to the Israeli Higher Command as he could discuss operational matters with them at their level and offer practical options. He stressed on the development of the intellectual standards of the officer army corps of the IDF and took steps to provide them with a University Education on government expenses. fortitude38. His sense of proximity to death explains leading aspects of his character. Further his cour age on battle field has been proven as the Chief of Staff. Within tailfin years, from 1948 to 1953 he climbed up to Chief of Staff from the battalion commander. He believed that the appointment means causing the general staff to become revolutionary. When he took up Israel Army in 1951 it was fed up after the failure of Tel Aviv against Syrian Army. He shook up it and changed in to an aggressive army with his starting signal of Chief of Staff.39. Moshe Dayan saw no need for American guarantees of Israels security and powerfully opposed Americas conditions, that Israel forswears territorial expansion and military retaliation. In an informal talk with the ambassadors to Washington, London, and Paris, Dayan described military retaliation as a vivification medicate to the Israel Army. First, it obliged the Arab governments to seduce drastic measures to protect their borders. Second, and this was the essence, it enabled the Israeli government to maintain a high degree of tension in the country and Army. earnestness40. As a young man he was a guard in the village fields, later joined the Haganah. Dayan was arrested in 1939, together with 42 of his friends, for participating in an illegal Haganah commanders course, and was sentenced to ten years imprisonment. Released in 1941, he joined a British Army unit lost an eye in a battle with Vichy forces in Syria. With all those incidents his enthusiasm took him to long way as an exemplary military leader.SELF-CONFIDENCE41. He suffered heavy criticism for not being prepared for the Arab attack during the Yom Kippur War in October 1973, Dayan became a controversial figure in Israel Although elected to the Ninth Knesset as a Lobour party member, he served as Foreign Minister in the beginning of the government until 1980-1981 elections he formed a new party, Telem, and stand for it in the Tenth Knesset. Many Israelis regarded Dayan as their countrys greatest military and political leader.ABILITY TO COMMUNICATE42. During the crisis preceding the Six Day War Dayan was appointed as Minister of Defense. After successfully conducting the War, Dayan administered the territories occupied by the Israel Army. He conducted a policy of liberal military government, opening the borders to trade and break between the occupied territories and Arab countries.OTHER SKILLS43. Dayan was the most fascinating and born leader who enjoyed more power during his leadership experience in both military and political. Although no one question about his overuse of power since he introduce totally new mechanism in military campaign as well in political campaign which helped to develop and tally the security within the Middle East. Besides it has been helped by his capability of well handling of language which able to negotiate his modernizing ideas with the audience.44. 1958 he was the Commander-in-Chief of the Israel Army. He successfully commanded the Israel forces throughout the Sinai Campaign of 1956. And also the entire Israeli military began to take on his personality. Dayan carried out a major reorganization of the Israeli army this is where he highlighted his great qualities of leadership of sound knowledge, planning capability and as an organizer. Dayan ended his Army service in 1958 and in the fall of 1959 was elected to the Knesset as a member of the Mapai party, and became Minister of Agriculture.COMPARISON WITH HIS COUNTERPARTSEVENTSMOSHE DAYANGAMAL ABDEL NASSERANWAR SADATHAFEZ AL-ASSADEarly intentEnthusiasm and gain much experience which lead to become a strong leaderAuare knowledge not the experienceAqure knowledge come profeciency and decentcy which help to become a peaseful leaderMilitary postman resolution and enthusiasmGain courage in revolution 1952Gain courage in revolution 1952Proficiency in Air force carrierAs the Chief of Staff companionship, modernizer and originator, Pride-CommandMinister of DefenceInitiative, plannerCooperation with Gamal, KnowledgeAs political leaderKnowle dgeKnowledge and courage during Suez crisis 1956, modernizer in politicsInitiative, peace negotiatorCunning, KnowledgeSix day WarInitiative, plannerFailure in Initiative and assessingFailure in assessingYom Kippur warSelf-confidence, loss of InitiativeInitiative, Enthusiasm45. Moshe Dayan was an Israeli military warrior and politician who became a supporter for peace too. He was skilled in not only battle but also diplomacy. He played a key role in four wars and also helped to negotiate the historic Israeli-Egyptian peace treaty. Gamal Abdel Nasser was the president of Egypt in the same era as opponent of Dayan. He took the power over Egypt by revolution and became president. He was the only one leader in the region to go against western countries over the Suez crisis in 1956. Anwar Sadat came to power in Egypt with the death of Gamal in1970 who supported Gamal to come in to power. Hafez al-Assad was the president in Syria in that era and he was respect the peace negotiations earli er than utilizes force to solve the Meddle-east crisis.KNOWLEDGE46. Moshe Dayan as a commander had a sound knowledge about own and enemy. He possessed perfect knowledge of his job too. He gains that knowledge from his carrier from the childhood, when he joined with Haganah and from rest of carrier up to became officer in the Army. Then he exercised that knowledge during his period of Chief of staff, where he renovated the IDF and also as an Agriculture Minister where he introduced a new mechanism which help farmers to reach supervises closely for the advices.47. When we consider the other counterparts, they were also had the same experience in their young life exempt Hafez, where they too able to acquire much knowledge. Gamal and Sadat both were worked in the Egypt Army together and had many experience their career. last mentioned they were utilized their possessed knowledge to become state leaders. Thereafter Gamal made many changes to economy in Egypt which country had lead towar ds development.MODERNIZER AND ORIGINATOR48. Dayan was the most fascinating and origin leader who enjoyed more power during his leadership experience in both military and political career compared to other triple leaders. He was always to introduce creative assets in any professional where he command or served without any reluctant. Although, Gamal Abdel Nasser was practice the quality of modernisation during his period of presidency to develop the economic aspect in Egypt. resolution AND ENTHUSIASM49. Dayan was the most courageous leader in that era in the region of middle-east. He proved that during his military carrier while he was conducting the operation Lidda and during Sinai campaign. And also as a Defence Minister during Six-day war. The following quotes which Dayan expresses clearly demonstrated his courage over the regionLet us not be afraid to see the hatred that consumes the lives of hundreds of thousands of Arabs who sit around us and wait for the moment when their hand s will be able to reach our blood.50. Gamal and Sadat too had quality of courage where they demonstrated during their revolution to become to power in Egypt. Although that, Hafez Al-Assad not showed much this quality during his carrier because he always respected the proficiency which lead to take peace rather than war in his life.SELF-CONFIDENCE AND INITIATIVE51. The most powerful leadership quality possessed by Moshe Dayan in his career. date he was perform in military, he always practice this quality all the same his higher(prenominal) authority disparate. It was significantly demonstrated in Six-day war against Egypt, Syria and Jordan defeating other leaders initiative and assessing capabilities. Gamal and Sadat too possessed with the initiative which they collected from military carrier. Then they took it to practice during their revolution against the government existed in 1952. Compared to all above terce leaders, Hafez had less experience on this aspect.PRIDE IN COMMAND5 2. This is the leadership quality which Dayan was able to attract the most of the people in the region towards him. And also entire Army also followed him as role model. study to Moshe Dayan other three leader never had this quality in their carrier. The following quote also emphasis his pride over command which he practiced throughout his life.Our American friends offer us money, arms, and advice. We take the money, we take the arms, and we decline the advice.COMPARISION WITHIN THE COUNTRY AS A POLITICAL LEADER53. Not only as a military leader but also as a political leader he succeeded. While he was performing as a Minister of Agriculture, introduce a new mechanism to enhance the field of agriculture in the Israel establish a planning authority, production and marketing council for each branch of agriculture. He made regional offices throughout the country where local farmers could receive agriculture guidance and services. This was where he saws his sound leadership qualities in out of military scenario where he proved that leaders are always created by the military.54. relatively to former agricultural ministers such as Kadish luz (1955-1959), Peretez Naftali (1952-1955), Levi Eshkol (1951-1952), who served in Israel, Moshe Dayan made hopeful magnificent contribution to enhance agriculture development during his period as agriculture minister. His experience, brilliant leader ship qualities and vast knowledge about the field paved way for systematical improvement in various field of agriculture.55. Once he was given another chance by Menachem Begin to undertake as Foreign Minister, he commence his work accept that he could significantly influence Israels moves towards achieving a peace arrangement with their neighboring Arab States and with the Palestinian inhabitants of Judea and Samaria and the Gaza Strip. During this period he was able to get all other counter pert to the peace table and he could make others to mean twice prior to take a decision a gainst Israel. And it paved way for disparities in between his Arab opponents.56. That differentiated the leadership qualities of Moshe Dayan from other contemporary leaders within the country and even from the region was significant.CONCLUSION57. Moshe Dayan who was born to the world on May 20, 1915 where is not having a piece of land even nationality for his people, he was able to build a country called Israel, piece by piece. He gave a county to people who did not have country. He gave a nationality to people who fought for their identity. Moshe Dayan became one of Israels most famous men and found fame as a military leader associated with victories that were seemingly impossible within theMiddle Eastconflicts. Dayan developed the aura of a military superman.58. Throughout Moshe Dayans life as an Israel military and political leader soma of leadership qualities can be identified and proved himself to nation long way from creating country for Jews even didnt had piece of land on their own. His courage, determination, knowledge, self confidence, enthusiasm, will power, integrity, loyalty, approachability build a country within another country, gave recognition to the nation Jews state Israel. Moshe Dayan was a good diplomat who believed peace, a hugely successful military leader who developed a legendary status. But he never forgot his ambition, once he stated his view on regular armyOur American friends offer us money, arms, and advice. We take the money, we take the arms, and we decline the advice.59. Dayans never forgot his nation, his country when liberating land from Arabs. He never forgot other nations in the world with keeping national strategy. Dayans career is probably unequalled in Israels short history. He successfully crossed over to politics and held a number of highly influential government posts before he left politics. senior military figures had tried to do the same move from the military to politics but many have failed.60. Moshe Dayan was a leader who is a leader of the sense of the word. He possessed several qualities through his whole life as one of the greatest leader in the history who became a legend in his own life time. He loved his enemy too. He always gave his warm hand for peace but with an bird of Jove eye. On 16 October 1981 this great leader General Moshe Dayan left the world to Shamayim (heaven) in Tel Aviv.

Sociological Imagination In Relation To My Life Sociology Essay

Sociological Imagination In relative To My Life Sociology EssaySociological imagery is germane to experiences of the psyche with new(prenominal) relationships in confederacy. There ar three primary characteristics of the sociological fancy history, biography and accessible expression. In correlation with Mills hypothesis of the sociological imagination, we will be able to position ourselves in reality and discombobulate enhanced understanding of ourselves and others through a grasp of the colligate among nearoneal experiences versus morphologic and historical forces (Mitra Sarabia, 2005). In this paper, I will encounter a critical contemplation on the factors that seem to hurl influenced my keep choices and chances. I will mathematical function my own personal encounters as a case necessitate and will use the sociological imagination as the tool for examination while realizing that this concept must be apply critically since I am attempting to link personal expe rience to domain issues (Schudson, 2008). Because of my carriage circumstances, the feminist point of view is the some useful attack although exemplary interactionism explains some(prenominal) of the issues I have encountered. The signalize sociological factors I have seen reoccurring in my research be anatomy, gender and enculturation. These pivotal factors of socialization have allowed me to unpack and feel forfully examine what the sociological imagination is, how it industrial plant based on my life experiences, and the panaches in which it connects to the geomorphological conditions in my life.The distinctive attribute of history cor bear ons to the ways in which a auberge was produced and how it has been transformed everyplace the course of m. The term Biography is an idiom for the benignant circumstances, or the nature of man in correlation to the type of individuals in a particular baseball club. Social structure defines the assure of a society focusing o n the people who are dominating, and how they cling together and how over cadence they change. The sociological imagination defines visionaries who can see beyond what is in front of them in relation to history, biography and social structure. (Mills, 1959, pg. 7)The theory of the sociological imagination facilitates an individual to associate their own life experience with the all of history along with social, economic, and political forces. The entire concept of the sociological imagination was summarized by Mills belief that the life of any single individual and the history of the whole society cannot be understood unless both are understood (Mitra Sarabia, 2005). This is because individual occurrences as thoroughly as all benevolent action is socially and historically contextualized. The central question concerns how we can lapse or apply the leap from individual experience to the entire society and to history. Schwalbe exemplifies how the social world must involve indiv iduals practicing a conscious causal agency of relating and unpacking their live experiences with society as a whole when stating how In the end, sociological mindfulness must be around more than studying how the social world realises. It must also do more than inspire curiosity, care and hope, it must help us change ourselves and our way of doing things. (Schwalbe pg. 43) The sociological imagination is best considered as a vehicle which permits use of one of the study sociological perspectives (Mitra Sarabia). In this case, it will be feminism but symbolic interactionism is relevant for this analysis. My parents primarily instilled certain values and beliefs especially concerning fairness and justice. The sociological imagination promotes critical thinking skills. The sociological imagination has refined my mightiness to think in relation to ground breaking new and innovational connections between myself and the society. A good metaphor by Allan G. Johnsons literary do sp urt The Forest The Trees and The One Thing exemplifies the sociological imagination as the lumber is society and the trees are individual people. How the trees are related to the forest personifies how individuals relate to society and societies history as a whole. Its crucial to understand the relationships among trees that make a forest what it is. Paying attention to that something more whether it is a family, potful or a whole society, and how people are interrelated to it is at the heart of the sociological dish out (Johnson, Allen, pg. 5)Social research is concerned with the translation and assessment of social phenomena. Social researchers enable us to get within these diverse social worlds and discover what social forces are at work in creating social life. (Duneier pg.53) Duneiers standpoint on the sociological imagination corresponds to the baring of my own personal sociological saga. As a college student I think to be successful you engage to have sociological imag ination. How oft do we sit in classes and wonder what the purpose of all this is? When many of us graduate from high school we see as farther as the premier day of college, we have no vision of our in store(predicate), we are looking to unhorse from our parents home and to find freedom and self expression. so in that location are others who graduate from high school and start their college public lifes. The first day of college is just another day for them, they are thinking about the life they will lead 10-15 old age in the future. They see their career exhalation a certain way, when they plan on getting matrimonial and having tiddlerren and some even see their retirement by the age of fifty. I find myself somewhere in the middle.I have always cognise I my dream duty was to become a writer from the time I picked up a pencil as a child I was in love with the feel of the pencil lead on paper. I took all the courses I could in physical composition and participated in wo rkshops and wrote for my topical anesthetic high schools paper read avidly. Upon graduation from high school I was focused more on making money, therefore I went to work and gave up writing. However, it did not take long before I went to college I quickly realized that if I requiremented to not work so hard for a minimal amount of money I would need to get a college degree in something that was practical yet gave me time to write.In college as I tried to choose a major I was still focused on making money quite a than being happy with what I was doing. I was determined to follow one of my passions and I picked Broadcast Journalism as my major because I could use my writing skills and do something I loved doing which was storytelling through interacting with people and reporting.I began comprehend my life in years rather than days. I began winning classes in subjects I liked. I am studying business as at the Whitman School and minoring in Entrepreneurship because I know this wil l be an imperative skill to have later in life. I keep pursuing my passion for writing however in my many needed arts and science elective classes, and have a plan for the years to come as how I take to make my living. I want to become either a sports spreader or a sports writer. I identified education as the key to change. The sociological imagination creates links between the personal the wider society in a reciprocal way. The person who has the sociological imagination is able to understand the large historical process in terms of its meaning for the inner experience and outer life of the individual. Schudson argues that the sociological imagination allows us to critically investigate reality rather of passively observing it. Andreev expands on that by explaining that individuals who are positioned at assorted social and economic points in society hold incompatible views of the world. hie argues that education is not always the solution but rather a source of new social an d economic inequalities since we can never escape from the factors of class, gender and race. As a result, the concept of the sociological imagination demand to be applied to a system of education as well to understand what impact that education will produce on different groups of people. I have found through my analysis that in order to use the sociological imagination and see a need for structural change, the person has to be oppressed or deprived in some way.With the internet there is no discrimination sociological imagination has secondary historical or biographical influence even social structure is irrelevant. The world of C. Wright Mills is disappearing on the internet people have no sociological imagination. People on the internet are dissolute becoming a society with no past or future there is just the present what is being done right at this moment. I want this type of life so does that mean I have sociological imagination in regard to the internet and how I will use it in my life. I know how the internet began and what it was to begin with used for, but does it influence my vision of how I am going to use it? No, when I am sitting at my laptop I dont think of the history of the internet or the people who use it. (Solis-Gadea, 2005, pgs. 113-122)When Im writing on my laptop I dont think of the people I am writing for or working for they have no face, no personality, no relevance to me except for giving me work. Social structure is nonexistent on the internet as well. No one has a face unless you want to and even then you cant be positive it is really their face.The way sociological imagination works in my life is by me seeing into the future and having a vision of myself working as a sports broadcaster or a sports writer. If sociological imagination is about making a connection to historical events and my instincts for the life I want then I would have to say I want a life hostile my parents., I do not desire to restrict myself and my lifes goals a job for 30-40 years because I have a mortgage and car payment, kids and a wife and the Joness living to the side of me. I want mobility and freedom and most importantly I want to utilize the technology that is out there to assist me in having the life I envision. (Schneider Silverman, 2006, pg. 43)The sociological imagination is expensive for allowing understanding of ourselves by way of the links between personal experiences versus structural and historical forces. Through reflecting on my life choices and chances with the use of the sociological imagination, I have been able to arrive at particular realizations. Power and class are at work in the wider society just as they are operating in my own life. Socialization was a key factor in my life because it guided me to connect with the underlying and structural conditions in my life. The sociological imagination promotes critical thinking skills, this idea to me means being able to think in terms of new and innovational conne ctions between myself and the society.Worked CitedMills, C.

Septic Shock Case Study: Causes and Effects

infected environop Case Study Causes and EffectsIntroductionSeptic Shock is a serious circulatory disorder often char effecterised by a whole- personate incitive state and the carcassic rejoinder to infection (Titheradge, 1998), with the most greens pee-pee being the contamination of logical argument with bacteria. Septic puff is delimit as sepsis with hypotension which develops in almost half(prenominal) of all unhealthful patients as a complication with a mortality rate of 40-60% (Titheradge, 1998).Septic seismic disturbance often results in a progressive failure of the circulation to ply course and oxygen to vital electric electronic organs of the body resulting in impai carmine waver perfusion and oxygen extr action at law (Thiemermann, 1997). The key symptoms embarrass a ascetic drop cloth in air pressure (hypotension) with hypo-re activity to vasoconstrictor agents (vasoplegia) which may check to the dysfunction or failure of major organs including lun gs, liver, kidneys and brain (multiple organ dysfunction, MODS) and in the end death (Goligorski et al., 1997).Presently it is widely assumed that pussy daze seldom shows similar symptoms in bear upon individuals and thusly it is difficult to detect and and then consequently treat it (Groeneveld and Thijs, 1986). It is, however, in summing up agreed that most of the sanative interventions incessantly focus on the primary aim of fighting the refractory hypotension by the use of aggressive fluid infusions, glucocorticoids, large doses of vasoconstrictors (Baumgartner and Calandra, 1999) and occasionally renal replenishment therapy (Wheeler Bernard, 1999). Yet these interventions do not offer consistent success (Parratt, 1997). In recent times, our understanding of the pathophysiology of septic shock has developed signifi send packingtly through and through experimental and clinical trials, though the denudation of a suitable word with therapeutic efficacy is proving elusi ve (Baumgartner and Calandra, 1999). This is probably because of the hetero componentity of the clinical moorings and the differences in host retort to identical pathogens. More all over bear witness suggests that different pathogens which cause septic shock respond differently to the received handlings. St feverous, no trend has been made to treat patients according to the nature of the infecting organism (Gao, Anonymous, 1992).During the early nineties azotic oxide (NO) emerged as a potentially upstanding step towards the treatment of septic shock. This determination directed scientists to carry out numerous clinical trials and animal experiments with the objective of finding out more about the interrelation of NO and Sepsis (Cobb, 1999 Kilbourn, 1999). Later, the disco very(prenominal) of nitric oxide synthase (NOS) made this enzyme the primary target of therapeutic agents (Rosselet et al., 1998). However, recently a substantial amount of literature has been published w ith evidence contradicting the discoveries of earlier studies. Today more than a decade has elapsed without any resolution to the matter and even in this 21st century Septic Shock is invading the development countries rapidly (Cobb, 1999 Kilbourn, 1999).This problem of a need of significant advances in this field can be extravagantlylighted by the position that 17 years have passed since the final publication of the Consensus Conference on sepsis and sepsis connect syndromes (Rangel-Frausto, 2005). This paper conclusively defined sepsis and its symptoms with the hope of finding a suitable treatment in order to eradicate the disease (Rangel-Frausto, 2005). Today, however, the situation has not changed significantly with up to 750,000 new sepsis cases twain year and 215,000 iodine-year deaths in the United States (Trzeciak et al., 2008, Mitchell M. Levy, 2007). Additionally, in the population that survives a great deal(prenominal) attacks, there is massive morbidity with many another(prenominal) scoring low in health related feature of emotional state assessments (Kaarlola et al., 2003, Perl et al., 1995). Hence the 5 million lives campaign instigated by the US Institute of Healthcare Improvements, aims to minimize the prevalence of nosocomial sepsis (sepsis originating in a hospital) (Gao et al., 2008). This campaign aimed specifically at change magnitude safety and trans constituteing the quality of hospital care (McCannon et al., 2007). Moreover, the Surviving Sepsis Campaign aims to improve the quality of life of septic patients using the best evidence available flowingly (Dellinger et al., 2004). though the world mortality rates have declined in recent times, sepsis is piecemeal becoming more prevalent in the elderly in the developing countries (Gao et al., 2008).This is mainly payable to the extended longevity of patients with chronic illnesses, the increase concomitant of immunosuppression, and the more frequent use of invasive proced ures (Bone, 1991 Parrillo, 1993). Sepsis, sedate sepsis, septic shock and multiple organ failure still dominate the mass cases of non coronary intensive care units (ICUs).This essay exit begin to explore the perfect mechanisms leading to tissue and organ damage in septic shock through the investigation of a case study. Following this, the discovery and public biology of nitric oxide (NO) shall be discussed, and the experimental evidence implicating NO as an effector in sepsis, testament be examined in detail. The results obtained from various pharmacologic interventions directed at NO in animal studies provide excessively be considered. This report will also give an account of conventional and innovative treatments for the management of septic shock. Finally, selective in governance from the few available pertinent clinical trials will be reviewed and possible future avenues of interest will be discussed.Systemic Inflammatory response syndrome and Septic Shock (Clinical Ma nifestation)Sepsis, severe sepsis and septic shock were inaccurately defined until a recently reviewed consensus assemblage in 1992 (Bone et al., 1992, Dellinger et al., 2004). In this meeting the term systemic seditious response syndrome (SIRS) was invented insinuating a clinical response arising from a nonspecific tissue change event (insult) (Rangel-Frausto, 2005).Sepsis as mentioned earlier is the result of substantial release of inflammatory mediators in response to an infection. However, often the same mediators are released in the absence seizure of a documented infected in several(prenominal) medical conditions such as cardiopulmonary bypass (Wan S. et al., 1997), pancreatitis and trauma (Shanley TP. et al., 2006). Due to this, the early definitions of sepsis or septic shock were free-base to be misleading and then a North American consensus convention proposed a new terminology. In this conference sepsis was defined as a condition in which critically ill patients mee t criteria for SIRS, in the context of infection. SIRS was defined as two or more of the following 1) heart rate 90/min 2) temperature 38C or 12,000 or 20/min or a PCO2 3.5 L min-1 M-23 2) hyperglycemia (plasma glucose 120 mg/dL) in the absence of diabetes 3) significant oedema or authoritative fluid balance (20 mL/kg over 20 h) 4) inflammatory variables plasma C-reactive protein 2 SD postgraduateer up the normal value or plasma procalcitonin 2 SD preceding(prenominal) the normal value and 5) mixed venous oxygen saturation (SVO2) 70% . (Dellinger RP et al., 2004). SIRS is mostly not considered as a disease and its recognition does not provide any clinical conclusion. However, since it has proven to be a very utilizable for the identification of sepsis and its sequelae namely severe sepsis and septic shock it is regarded as a very all grievous(predicate) tool (Shanley TP. et al., 2006).Case StudyA 3-year-old boy was admitted to the intensive care unit because of fever, hypot ension, and lethargy. A purpuric rash was noted on his arms and legs. arterial pipeline accelerator analysis demonstrated hypoxemia and metabolic acidosis. The arterial lactate level was 10 m breakwater/L. He was intubated, resuscitated with crystalloid solution, started on broad-spectrum antibiotic therapy, and given dopamine to maintain a MAP above 55 mmHg. His chest radiograph revealed bilateral interstitial-alveolar infiltrates with a left sided predominance. one thousand stain of the cerebrospinal fluid showed gram-negative cocci. The dopamine infusion was increase to 18g kg-1min-1 for persistent hypotension and oliguria. Pulmonary and radial arterial catheter data yielded the following o kioskus pressure, 85/30 mm Hg MAP, 48 mm Hg heart rate, 140 beats per minute CVP, 10 mm Hg pulmonary artery pressure, 22/14 mm Hg PCWP, 12 mm Hg cardiac tycoon, 2.5L min-1m-2 and SVRI, 1226 dyne-sec-cm-5m-2. The boy was enured with additional saline and an epinephrine infusion, which in creased the MAP, cardiac index, and urine output. Arterial lactate levels decreased over the next 12 hours. Subsequent cultures of blood and cerebrospinal fluid grew Neisseria meningitidis.In this case the patient with acute organ failure and hypotension was diagnosed with septic shock. The young boy with meningococcal septic shock had a borderline-low cardiac index. Due to this a decrease in the cardiac index in this patient by the administration of an NOS inhibitor might not be desirable. This is suggestive of the fact that NO or its price reductioning means cannot always be targeted in order to battle septic shock. I will attempt to go into further details with regards to this statement as we go along the essay.azotic Oxide discoveryJoseph Priestly first identified gaseous NO in 1772. NO also named Nitrogen Monoxide is a very unsubdivided and tiny scrap consisting of one nitrogen and one oxygen molecule. unfathomable of its fundamental physiological occasions in the mammals, until the 1980s NO was widely considered as a mere toxic atmospheric pollutant (Konstantin J. Ovodov et al., 2000).In the 1980s researchers were examining how blood vessels expand (dilate) hence regulate the mean arterial blood pressure. distention of blood vessels, also termed vasodilation is a very important physiological response which partly regulates the blood pressure. By increasing the diameter of blood vessels, vasodilation causes the blood to travel more freely due to glower resistance (RF Furchgott, 1980). Since the blood vessel lm widens during vasodilation, the blood imposes less outward pressure on the vessel wall hence reducing the blood pressure. In opposition, vasoconstriction reduces the diameter of the lumen increasing the BP. These physiological responses occur all the time in the kind-hearted body regulating the BP and therefore are one of the most fundamental mechanisms of the human body.Dr Robert Furchgott and his group, later in 1980s investigated the role of acetylcholine in the sedate musculus relaxation and ready that relaxation only occurred if a special class of carrels called endothelial mobile phoneular telephones were re tress (RF Furchgott, 1980). These cells line the interior turn up of blood vessels, forming an interface in the midst of circulating blood in the lumen and the rest of the vessel wall. Behind the endothelial cells are the smooth muscle cells which either relax or contract thus regulating the vascular tone (RF Furchgott, 1991).The same research group also discovered that smooth muscle were only able to vasodilate the blood vessels in the presence of endothelial cells. This indicated that there was some kind of factor that was being released by the endothelial cells which was knobbed in the dilation of the blood vessel. This factor was named Endothelium Derived Relaxing instrument (EDRF) and subsequently specified as NO (S Moncada et al., 1997).In 1977, Ferid Murad independantly investigated the mech anism of action of nitroglycerin and found that it worked by inducing the release of NO which in turn was able to cause relaxation of smooth muscle cells (F Murad et al., 1977).Louis Ignarro in 1986 finally resolved the whole perplex of EDRF and NO by declaring that EDRF was in fact NO. It was stated that both molecules showed identical properties when he compared gas Nitric Oxide and EDRF (Ignarro, L. J. Et al. 1987). In 1998, Nobel Prize in Physiology and Medicine was awarded to Drs. Robert Furchgott, Louis Ignarro, and Ferid Murad for their discoveries that vascular endothelial cells make nitric oxide (NO) and that such endothelium-derived NO stimulates cyclic guanosine monophosphate (cGMP) deductive reasoning in the underlying vascular smooth muscle, causing relaxation (Kilbourn, 1999).Since the discovery of NO, vast number of its physiological roles in normal conditions have been report including in the repellent system, aflutter system, reproductive system and other cellula r functions. It has also been found to interpret important roles in variety of species ranging from mammals, to insects and plants. section of Nitric Oxide in BiologySince it was first discovered to play a role in the dilation of blood vessels many new roles for Nitric Oxide (NO) have been discovered. In human body, NO is metabolised by its diffusion into red blood cells where it oxidizes the ferrous iron of oxyhemoglobin yielding methemoglobin and nitrate ions (NO3-) (J.M. Hevel et al., 1994 and Konstantin J. Ovodov and Ronald G. Pearl, 2000). This m individuallyanism limits local NO build up and is particularly important in tutelage NO concentration in naomolar range, at least in nonhydrophobic compartments (i.e. out of doors cell membranes) (Beckman Koppenol, 1996). Nitric oxide has been found to be shitd by effectively every cell eccentric person in vivo and plays an important role in both controlling the normal function of cells as well as in regulating larger scale proc esses such as the reproductive, repellent and nervous systems. A few of these biological functions for NO are described in more detail infra.The Immune SystemNitric oxide plays many important roles in the immune system although it is show in many cell types following endotoxin or pro-inflammatory cytokine treatment (C. Nathan et al., 1991 and R.G. Knowles et al., 1994). NO, in immune system, is maked in high amounts from specific cells called macrophages. Proceedingly to an infection, chemicals kn make as cytokines are release in vivo which activate the cells of the immune system such as macrophages, and help level them to the site of infection (S. Moncada et al., 1991 and C. Nathan et al., 1991). NO produced by the macrophages is toxic to the bacteria and play an important role in their destruction ( common fig 1). The occupation of nitric oxide in this way also helps protect against other types of infection including parasites and viruses (S. Moncada et al., 1991).However, too much nitric oxide production can not only lead to septic shock notwithstanding has also been implicated in conditions where the immune system is too active autoimmune diseases like arthritis (Jang D and Murrell G A, 1998).The ill at ease(p) SystemNitric oxide has been shown to be knobbed in both the computer peripheral and central nervous system. The three nitric oxide producing isotypes of enzyme (iNOS, eNOS, nNOS) (see section) in humans, one isotype (neuronal NOS (nNOS)) is found almost exclusively in the nervous system (Forstermann et al., 1995). nNOS is thought to be involved in promoting the transfer of interneuronal nerve signals. This is thought to take typeset by the stimulation of exocytosis (release) of endogenic chemicals called neurotransmitters of one neurone (Moncada et al., 1991 Forstermann and Kleinert, 1995). These NT then diffuse crosswise the synaptic cleft (gap between neuronal terminals) and stimulate the neighbouring nerve cell terminal to transmit t he signal (Otto Loewi, 1961). NO has shown to play a substantial role in diseases of the nervous system like Alzheimers and Parkinsons. In both diseases, the inhibition of NO has shown to slow down the progression of the disease in mice (Weill Cornell Team, 2005 and Johns Hopkins et al., 2004).Reproductive BiologyNitric oxide is one of the most important molecule in the course of reproduction and is involved in many aspects of it. As well as dilating the blood vessels and thereby helping to regulate motherlike blood pressure, NO is also involved in implanting the early fertilized egg in the uterus (Rogers, 1995). During pregnancy, nitric oxide is also suggested promote angiogenesis (a process in which new blood vessels are formed) (RayChaudhury et al., 1996). It is also known to play a role in the survival of trophoblasts (form placenta) (Enders et al., 1978). Furthermore deficiency of NO has been found in patients with preeclampsia (a medical condition in pregnancy) suggesting its partial role in growth of embryo (Yallampalli et al., 1994 Liao et al., 1996). In addition, drugs (Viagra) used to treat cavernous dysfunction also affect nitric oxide signalling.Cellular functionA notable number of cellular activities can be controlled by nitric oxide including cell division, cell movement and cell survival.The majority of cells in human body have the ability to undergo programmed cellular death. This is a dangerous mechanism usually called apoptosis which often occurs when a cell is modify and beyond repair, infected with a virus, or undergoing stressful conditions such as starvation (Kerr et al., 1972). Cells in these conditions go through apoptosis so that they dont stay the proper functioning of the rest of the tissue. During apoptosis, the structures of the cell break down in an organised manner, forming a packaged cell that is smaller in coat so that it can be easily removed by the cells of the immune system (Kerr et al., 1972).Nitric oxide was first sho wn to inhibit apoptosis hence promoting cell survival in human B lymphocytes (Mannick, J. B. Et al., 1994). Subsequently similar finding were reported in an ample number of other cells. However, high doses of nitric oxide also have deleterious effects. They can be toxic to many cell types and can lead to septic shock and multiple organ dysfunction syndrome (MODS) in which case NO causes cell death preferably of promoting cell survival (Beal Cerra, 1994).Nitric Oxide and Inflammation (Pathophysiology of septic shock)This section will deal with mechanism by which wall fragments of Gram-negative or Gram-positive bacteria and other inflammatory agents induce nitric oxide synthase (iNOS) in cells and tissues. exogenous toxins which enter the circulation stimulate the synthesis and release of a number of endogenous cytokines. During a gram-negative infection which can lead to septic shock, lipopolysaccharide (LPS) and endotoxins present on bacterial wall and many other inflammatory agen ts cling to a co-sense organ (CD14) on the surface of specific immune cells like macrophages, resulting in their activation (J.C. Lee et al., 1996). LPS also maintain to LPS-binding proteins which are produced by the liver. These proteins comfort LPS binding to the CD14 co-receptor of the macrophages. The CD14 co-receptor is excited through the binding of LPS to a toll-like molecule (TLR4), (Re F, Strominger J. Et al., 2001) which is trusty for initiating the transmembrane signaling. TLR2 molecules act in the same way as TLR4, (Leppper PM et al., 2002) though these are activated by gram-positive bacteria, mycobacteria and yeast. Gram-positive bacteria such as Staphylococcus aureus have further additional wall fragments such as peptidoglycan (PepG) and lipoteichoic acid (LTA). Both PepG and LTA have been shown to synergise to produce the lineament features of septic shock, MODS and finally death in rodent models (S.J. De Kimpe et al., 1995 and G.M. Millar et al., 1997). These ef fects were not observed with either LTA or peptidoglycan alone, although high doses of LTA can cause circulatory failure but not MODS (S.J. De Kimpe et al., 1995). Gram-positive bacteria may also release other enterotoxins and exotoxins, for example toxic shock syndrome toxin 1, which are involved in the pathogenesis of sepsis (reviewed in (R.C. Bone et al., 1994)).The additional fragments released by Gram-positive bacteria bind to unknown receptors however, like LPS binding, cause the release of proinflammatory cytokines tumor necrosis factor-a, IL-1, and IFN-? (Thiemermann, 1997, Titheradge, 1999). These cytokines as well as IL-6 are often produced in response to immune stimulation of macrophages and monocytes hence also in septic shock patients.IL-1 and tumor necrosis factor each occur in two forms, a and . tumour necrosis factor- a and both forms of IL-1 are made by activated monocytes and macrophages, whereas TNF- is made by activated T lymphocytes (Review by J. Saklatvala et al., 1996). There are two receptors for both IL-1 and TNF and the two forms of each cytokine interact with the same receptors. IL-1 a and interact with the type 1 IL-1 receptor for signal transduction, whereas type II does not bulge out to transmit any signal and functions as an inhibitor of IL-1 action (J. Saklatvala et al., 1996). The two types of TNF receptor, p55 (type I) and p75 (type II) have different end effects p75 mediates the proliferative actions of TNF- a while p55 receptor signals the inflammatory response and apoptosis (J. Saklatvala et al., 1996). Complex interactions between these different mediators produce intense pathophysiological modification, which eventually lead to diffuse tissue injury and ultimately sequential system failure (multiple organ dysfunction syndrome), which accounts for the majority of deaths among patients with sepsis, severe sepsis and septic shock (Beal Cerra, 1994).IL-1 and TNF-a have a very curtly half life compared to IL-6 and theref ore IL-6 is a very good indicator of cytokinemia. The sign studies of septic shock, showed a very strong positive correlation between IL-6 levels and fatal outcome (Casey L. Et al., 1993). NO is equally a very short lived molecule with an estimated in vivo half life of only 0.1 seconds hence again it is hard to measure its levels in order to detect the severity of cytokinemia hence the severity of sepsis or septic shock. There are several molecules that founder to the pro and anti-inflammatory responses in septic shock (Table 4) however I shall only focus on a few due to the express word allowance.In response to inflammatory agents in septic shock, the released cytokines (TNF-a, IL-1, and IFN- ?), bind to their specific receptors activating a protein kinase called tyrosine kinase leading to both the activation of the nuclear factor-kB (NF-?B) (a transcription factor) and the phosphorylation of intracellular protein (Gao et al., 2008). A precise mechanism by which these cytokines act was proposed by J. Saklatvala et al. in 1996 however this has yet to be confirmed.Nitric oxide producing cells have got I-?B which is an inhibitor of NF-?B. For the activation of NF-?B, proteolytic cleavage of I-?B from NF-?B is demand which forms NF-?B. This biological change allows the activated NF-?B to translocate to the nucleus, where it binds to the promoter component of the iNOS gene inducing transcription. It has also been reported to induce other inflammatory agents, such as cytokines and leukocyte-endothelial adhesion molecules (Janssen-Heininger et al., 2000). Tyrosine kinase present inside the cell acts as a messenger molecule involved in the proteolytic cleavage of I-?B/NF-?B and hence in the activation of NF-?B and iNOS view (Hecker M, et al., 1996). In septic shock, the translated products of iNOS mRNA subsequently assemble forming the iNOS protein which in turn causes local NO proliferation (Thiemermann, 1997). Fig 2 shows the signal transduction pathway of iNOS rule in response to inflammatory agents.The physiological role of iNOS is to enhance the formation of NO (due to iNOS activity), which in turn may contribute to either the pathophysiology of septic shock (clinbical symptoms) or the host defence (Reviewed in Gao et al., 2008). Fig 3 shows a simplified schematic of the Anti Inflammatory cascade in the context of septic shock.Excess NO produced by iNOS has been reported to both induce and inhibit NF-?B (Kalra et al., 2000 Umansky et al., 1998). In year 2000, it was proposed that low levels of NO may induce further NO production while high concentrations do the opposite exhibiting a feedback mechanisms that would oppose the over expression of genes adjust by NF-?B (Janssen-Heininger et al., 2000). In addition NO at high concentrations competes with O2 at the active site of NOS, thus providing a feedback mechanism of its own synthesis (Griscavage et al., 1995 Rengasamy Johns, 1993).Biological Synthesis of Nitric Oxide (Nitric Oxi de Synthases)NOS structure and substrates for NO productionIn mammals, NO is exclusively formed from the enzymatic oxidation of one terminal guanidino nitrogen of the amino acid L-arginine. When expressed in moles, this reply utilizes 1 mol each of arginine and O2, and 1.5 mol of NADPH, yielding 1 mol of NO, 1 mol of L-citrulline and 1.5 mol of NADP (R.G. Knowles et al., 1994). The reaction sequence involves the generation of an Ng-hydroxy-L-arginine intermediate, followed by the oxidation of Ng-hydroxy-L-arginine in presence of molecular oxygen to form L-citrulline and NO (Dennis J. Stuehr et al., 1991 and R.G. Knowles et al., 1994).The enzymes that accelerate the reaction above are a family of comparatively large protoheme proteins known as NO synthase (NOS) which resemble cytochrome P450 structurally (M. M. Chan et al., 2001 and Francois Feihl, 2001) (The general mechanism of NO production from NOS is illustrated in Fig 4). every(prenominal) members of this family share a simi lar homodimeric structure, where each monomer consists of a an oxygenase domain and a reductase domain, separated by a short amino acids (30aa) sequence for the alliance of the Ca2+-binding protein calmodulin. In addition to calmodulin attachment, enzymatic activity requires the presence of four cofactors FAD, flavin mononucleotide (FMN), tetrahydrobiopterin (BH4), and heme (Francois Feihl, 2001). Fig 5 shows the general structure of the NOS enzymes.Nitric Oxide Synthase isoforms and their locus in the Human BodyThere are three known isoforms of NOS, each the product of a different gene neuronal NOS (nNOS or NOS-1), inducible NOS (iNOS or NOS-2), and endothelial NOS (eNOS or NOS-3). nNOS and eNOS were first described in rat cerebellum and bovid aortic endothelial cells, respectively, but their tissue dispersal is far wider than suggested by their names. eNOS and nNOS are involved in regulating vascular tone (R.G. Knowles et al.,1992 and S. Moncada et al., 1991) and neurotransmissi on respectively, whereas iNOS is involved in the immune defence although it is expressed in many cell types following endotoxin or pro inflammatory cytokine treatment (R.G. Knowles et al., 1994).nNOS is typically expressed in skeletal muscle and myenteric plexuses. eNOS is ubiquitous in vascular endothelium, but may also be found in the kidney tubular epithelial cells, placenta (Forstermann et al., 1995), and neurons (Nathan Xie, 1994). In these tissues, the expression of nNOS and eNOS is constitutive, although it may be regulated (Michel Feron, 1997). For instance, the levels of transcript for eNOS in vascular endothelial cells is increased by shear stress (Topper et al., 1996 Uematsu et al., 1995) and perform (Wang et al., 1997), reduced by inflammatory stimuli such as TNF-a (Nathan Xie, 1994) and variably affected by hypoxia (Le Cras et al., 1998 Toporsian et al., 2000). In the physiological state, the iNOS isoform is only present at a few locations, notably the respiratory e pithelium, the gravid uterus (Nathan Xie, 1994), and perhaps the ileal mucosa (Hoffman et al., 1997). iNOS expression has been demonstrated in numerous cell types including macrophages, neutrophils, vascular endothelial (Hoffmann et al., 1999), smooth muscle cells, endocardium, myocardium, fibroblast, mesangial cells, renal tubular epithelium (Kunz et al., 1994), neurons, hepatocytes, pancreatic islet cells and astrocytes (Nathan Xie, 1994). iNOS can be induced by a number factors including UV light cyclic AMP-elevating agents trauma ozone and bacterial products described earlier (see section). On the other hand, many endogenous agents may oppose cytokine induction of iNOS. These include anti-inflammatory cytokines such as IL-10, chemokines such as monocyte chemoattractant protein-1 and growth factors such as tumor growth factor- (Forstermann et al., 1995). In all NOS isoforms, calmodulin binding is an perfectly vital for enzymatic activity. In the cases of eNOS and nNOS, this b inding necessitates relatively high concentrations of Ca2+ (see Fig 7), in the range of 0.1-1 mM (Forstermann et al., 1995). In contrast, iNOS is able to bind calmodulin approximately independant of Ca2+ (Table 2). Therefore, once iNOS is expressed, NO synthesis may only be throttle by the availability of substrates and cofactors (J. Stuehr, 1990). As NO produced from iNOS predominantly depends only on iNOS expression, it lasts much longer than NO formed from the other isoforms of NOS. In addition iNOS produces much higher concentrations of Ca2+ compared to the consecutive forms of NOS (Cobb et al., 1996). The production of NO by eNOS and nNOS, compared to iNOS, can be controlled relatively easily by decreasing or increasing intracellular Ca2+, whereas iNOS can only be controlled through transcription (Cobb et al., 1996). In most cell types iNOS protein levels are either very low or undetectable. However, stimulation of these cells by cytokines or growth factors, can lead to incre ased transcription of the iNOS gene, with subsequent production of NO. On the other hand, for the taproom of iNOS expression through endotoxins, TGF- (Szabo, 1995) and anti inflammatory glucocorticoids can be administered which lower the magnitude of vascular hyporeactivity. Glucocorticoids such as Dexamethasone inhibit iNOS activity by blocking arginine post and inhibiting tetrahydrobiopterin biosynthesis (A.J.B. Brady et al., 1992 and Thiemermann C et al., 1993).Regulation of NO productionIn the normal as well as in extreme physiological states (e.g. during infection), nitric oxide is considered as one of the most important signalling molecules in vivo. It is however also highly reactive and highly diffusible due to it being a free radical (one unpaired electron) (see fig 8). It is therefore important that there is strict control and regulation of nitric oxide production. The synthesis of NO within cells can be regulated in several ways such as the cellular distribution of NOS, changes in NOS gene expression, enzymatic activation by phosphorylation and the presence of cellular inhibitors NOS activity.Intracellular distribution of NOSNitric oxide is principally regulated through strict control over the location of NO production.The NOS isoforms can be targeted to different regions of the cell, where NO will be produced in close contact with its target proteins. The image below shows the distribution of iNOS (shown in green in image 1) and eNOS (shown in red) in a trophoblast cell. The nucleus is shown in blue. Co-localisation between iNOS and eNOS will show up as a yellow colour (Phil Dash, University of Reading).The image shows that eNOS and iNOS are middling variably distributed inside the cell, with hardly any yellow colour suggesting very little overlap in their cellular distribution (Phil Dash, University of Reading).Although both iNOS and eNOS produce NO it is presumable that their different cellular distribution will lead to NO interacting with dif ferent targets and therefore having different effects (Phil Dash, University of Reading).It is very likely that the distribution of NOS isoforms is an important mechanism for regulating when and where NO is produced. Therefore the current research on NOS mainly focuses on how endogenous signals trigger NOS transport and redistribution (Rahul S. Koti et al., 2005).Activation of NOS activityNOS enzyme synthesis is principally regulated by changes in intracellular calcium levels. The constitutive isoforms of NOS, (eNOS and nNOS) have shown to proliferate following increases in Ca2+, and therefore calmodulin levels, in the cell (Rameau et al., 2003). Additionally both nNOS and

Laminar Air-flow to Control Operating Room Infection

Laminar Air- light to keep in line Operating Room InfectionINTRODUCTIONSurgical site transmittings (SSIs) atomic number 18 defined as contagions occurring within 30 days after operative working(a) routine or within star year if an implant is leftfield in place and affecting either the incision or incomprehensible tissue at the operation site (Owens and Stoessel 2008). SSIs argon reported as the major ca commit of high morbidity and mortality among post -operative patients (Weigelt et.al. 2010). tally to UK National Joint Registry Report, during 2003 -2006 flow transmission was amenable for near 19 % failure of joint functioning forgeting in revision procedures (Sandiford and muleteer 2009).Micro-organisms in the phone line power particles pin down on the wound, dressings and running(a) instruments and cause transmittals (Chow and Yang 2005). Whyte et.al (1982) identify that taint from patients skin as the cause of infection in 2% cases and from orbit personn el in 98% cases. They in corresponding manner demonstrate that in 30% cases, contaminants reach the wound from airfield personnel via air and in 70% cases it is via hands.Generally air quality in the direct path is maintained external respiration establishment. Additional amendments cornerstone be achieved by stratified air- lam system of rules or UV lights. Laminar air-flow system is expensive and adopt continues maintenance. Its installation increases building cost and the operational cost (Cacciariet.al., 2004 Hansen, 2005). Studies conducted to evaluate the durability of bedded flow produced mixed results and on that point is no consensus on its parting in infection tally (Sandiford 2007). In this even outting, this paper go offs the recent studies to judge the strong point of stratified air-flow in diminution SSIs.Studies for this review were pitch by searching on databases such(prenominal) as CINAHL, PubMed, Science Direct, Ovidsp, Science credit entr y Index (ISI) and Google scholar. Keywords employ for this search are stratified air flow, surgical site infection, operating room air quality, airborne infections + operating theatre, LMA + infection control. As laminar air-flow is used mainly in orthopedical theatres, majority of the studies are on joint military operation.OPERATING THEATRE AIR forest AND INFECTION CONTROLIndoor air in an operating theatre contains dust which consists of substances released from disinfectant and sterilizers, respiratory offloadlets, insect parts smoke released from cautry. form particles act as a carrier for transporting microorganisms laden particles and shtup settle on surgical wound and in that location by cause infection (Neil 2005). Air particles are plant to be responsible for ab knocked out(p) 80% 90% of microbial befoulment (CDC 2005).Modern operating theatres are more than often than non equipped with conventional internal respiration system in which filters hobo pack airborne particles of sizing 5mm round 80-95% (Dharan 2002). The efficacy of operating room ventilation is measured by the colony forming units (CFU) of organisms present per cubic meter. The conventional ventilation (Plenum) with 20 air exchanges is considered efficient if it achieves the colony count of 35cfu/m3 or little (Bannister 2002).Ventilation system with laminar air-flow directs the air-flow in unrivaled direction and sweeps the air particle over the wound site to the exits (CDC 2003). Laminar air-flow with HEPA (High Efficiency particulate matter Arrestment) filters system has the capacity to remove air particles of size 0.3 m up to 99.9 % and can produce 300 air exchanges per hr in ultra reave orthopaedic theatres. (Sandiford and skinner 2009).Laminar air-flow units are oecumenicly two types ceiling-mounted (vertical flow) or wall-mounted (horizontal flow). there are inconveniences associated with both types. Generally the major problem associated with laminar air -flow is flow chop offion. With vertical laminar flow, it is the heat generated by surgical lamps creates air upthrust epoch with horizontal laminar flow it is the surgical team that disrupt the air-flow (Dharan 2002).LAMINAR AIR FLOW IN INFECTION CONTROLLLaminar air-flow system is mainly used in implant surgeries where even a abject number of microorganisms can cause infection. In joint replacement surgeries, one of the main causes of early (within 3 months) and delayed (within 18 months to 2 years) tardily prosthetic infections was instal colonisation during surgery (Knobben 2006). Laminar air flow is supposed to minimize pollution by mobilizing uniform and elephantine book of account of wise air to the surgical area and Contaminants are flushed out instantly (Chow and Yang, 2004). Some studies shew that this method is effective in trim infection but some others produced contradicting results (give some reference)A recent teaching conducted by Kakwani et.al. (2007) f ound that laminar air-flow system is effective in bring down the reoperation rate in Austin-Moore hemiarthroplasty. Their cogitation compared the reoperation rate surrounded by theatres with laminar air-flow and theatres without laminar air-flow system. A cohort of 435 patients who had Austin-Moore hemiarthroplasties at Good Hope Hospital in Birmingham between August 2000 and July 2004 were selected for this education. Of those 435 patients, 212 had operation in laminar air-flow theatres and 223 had operation in non-laminar air-flow theatres. selective data were collected by reviewing case notes and radiographs. For all cases antibiotics were administrated and water mothproof surgical gowns and drapes were used. In the non-laminar air-flow mathematical group it was found that the re-operation rate for all reference in the premiere year after hemiarthroplasties was 5.8 % (13/223), while in the laminar air-flow group it was 1.4% (3/212). Analysis found that there were no stati stically real relation between re-operation rate and water impervious gown and drapes (p=0.15), while use of laminar air-flow found a statistically hearty drop (p=0.0285) in re-operation rate within the first year after hemiarthroplasties. They found that re-operation rate in no-laminar air-flow theatres were four snips greater than that in laminar flow of air theatres.Even though the aim of the study was clearly describe there was no review of existing studies to identify the gap in the research. Study methods and details of statistical digest were given elaborately. The sample size seems sufficient. Results were summarized and presented using graphs and charts. Discussion of results was short and seems not adequate to address the objectives of the study. on that point was no attempt to explain the casual relationship. For example researches were making statements such as the introduction of water-impervious drapes and gowns did not seem to make a statistically significant im provement in the result. (p.823). Researchers failed to acknowledge either limitations of the study. Data for this study was collected by reviewing patients records. Patients records are considers as confidential and researchers didnt conjure whether they received consent from the patients or honorable approval form intromission to conduct the study. This can be considered as an ethical flaw of this study. there are studies which found that laminar air-flow system is not effective in minify infection rate. In their study Brandt C et.al (2008) found that infection rate was substantially high in theatres with laminar air-flow system. This was a retroactive cohort-study based on routine management data from German study nosocomial infections surveillance system (KISS). Hospitals which had performed at least 100 operations between the years 2000 and 2004 were selected for this study. Type of ventilation technology installed in operation rooms of selected hospitals were collected separately through and through questionnaire from infection control teams in the participating hospitals. Surgical departments were grouped into categories according to the type of ventilation system installed. Departments using artificial operating room (OR) ventilation with either nettled or laminar flow of air was included in this study. arrive 63 surgical departments from 55 hospitals were included in this study. Analysis was performed to the data set created by merging the questionnaire data on OR ventilation and surveillance data from the KISS data base. The data set analysed contained 99230 operations with 1901 SSIs. bestride and gender of the patient was found a significant lay on the line grammatical constituent of SSI in most procedures. Univariate analysis conducted found that rate of SSIs was high in departments with laminar air flow ventilation. Multivariate analysis withal sustain this finding. Authors argue that it may be due to the improper positioning theatre personnel in horizontal laminar flow room.Researches provided a well-researched writings review which clearly identified gap in current research. Objectives and architectural plan of the study was properly explained. Study was based on a large sample size. Results were discussed in detail and casual relations were well explained. seemly tables were used to present results. Limitations were properly discussed.Knobben et.al (2006) conducted an experimental study to evaluate how general changes in concert with behavioural changes can decreases intra-operative contamination. This study was conducted in the university Medical center Groningen, The Netherlands. A hit-or-miss sample of 207 surgical procedures which involved total knee joint or hip prosthesis from July 2001 to January 2004 was selected for this study. cardinal sequential series of behavioural and systemic changes were introduced to ascertain their role in reducing intra-operative contamination. The control group co nsisted 70 cases. Behavioural changes (correct use of plenum) were introduced to the first intervention group of 67 operations. Intense behavioural and systemic changes were introduced to second intervention group of 70 operations. The systemic changes introduced was the installation of new laminar flow with improved air flow from 2700m3/h to 8100m3/h. Two samples each were interpreted from used instruments, unused instruments and outback(a) bones. Control swabs were also collected to make sure that contamination was not occurred during transport and culturing. Early and late intra-operative contamination was also pauseed. All patients were monitored for whatever wound deport while in hospital and followed-up for 18 months to check whether intra-operative contamination affects post-operative infection.Among the control group contamination was found 32.9% while in intervention group 1 it was 34.3% and in intervention group 2 it was 8.6%. Except in Group 1 (p=0.022) late phase co ntamination was not definitively higher than early phase contamination. During the control period wound discharge was found in 22.9% patients and 11.4% of them had wound infection later. thick(p) periprosthetic infection had been found in 7.1% of them in the follow-up period. Deep periprosthetic infection was found in 4.5% cases of first intervention group and in 1.4% of cases in second intervention group in the follow-up period. But no(prenominal) of these decreases were found statistically significant. Contamination, prolonged wound discharge and superficial surgical site infection were found decreased after both first and second intervention. But a statistically significant reduction was found but in second intervention (contamination p=0.001, wound discharge p=0.002 and superficial SSI p=0.004). This study concluded that behaviour modifications together with improved air flow system can reduce intra-operative contamination substantially.Purpose of the study was clearly defin ed and a good review of the current literature has given. Gap in current research was clearly presented and justification for the study had given. Sample size seems sufficient. It is reported that .bacterial lasts were taken during 207 random operations (p. 176), but no details of the sampling method used were provided. Details of interventions were given elaborately and results were discussed in detail. But simply one table and two charts used to present it. The readers would have been more benefited if more tables were used to present the results. Discussions of the results were concise and findings were particular(prenominal) and fiting the objective. No information on whether they received informed consent from the patients and approval form the ethical committee of the institution was missing. This arise a serious question about the ethics of this study.It is found that laminar flow of air is more effective when use in conjunction with occlusive clothing (Charnley, 1969 cit ed in Sandiford and Skinner 2009). period in their recent study Miner et.al (2007) compared the forcefulness of laminar airflow system and bole exhaust suits found that remains exhaust suits are more effective than laminar flow system in reducing infection.For their study Miner et.al (2007) selected 411 hospitals which have submitted the claim for total knee surgery (TKR) for the year 2000 from four US States were surveyed to collect the details of use of laminar air flow system and body exhaust suits. Those hospitals which were fulfilled trey criteria were included in this study. The inclusion criteria were 1) returned the survey instrument, 2) using laminar air flow system or body exhaust suits for infection control and 3) was evidence of at least one Medicare claim for TKR for the study period. Total 8288 TKRs performed in 256 hospitals between 1st January and 30th August 2000 were selected. Data on patient outcomes after total knee replacement (TKR) were collected from Medi care claims. The patients who underwent isobilateral TKR were not included in this study and for those who underwent a second TKR during a separate hospitalisation during the study period, just now the first procedure was included. outside(a) Classification of Diseases, Ninth Revision (ICDS-9) codes was used to identify post-operative deep infection that needed superfluous operation. Hospitals were grouped as users or non-users for both laminar airflow and body exhaust suits. Users were defined as those who use any of these methods in more than 75% procedures and non-users were those use any methods less than 75%. The over-all 90-day incidence of deep infection, subsequent operation was found required only in 28 cases (that is 0.34%). Analysis found that the risk ratio for laminar airflow system was higher (1.57, 95% confidence interval 0.75-3.31) than body exhaust suits (0.75, 95% confidence interval 0.34-1.62). Study found that there were no significant differences in infecti on between hospitals that use specific either protective measure.Other than mentioning few studies researchers failed to provide any ambit of the research problem. Methods used for this study were explained concisely. Even though the sample size was large, limited number of events (28) were there to be observed. Analysis was based on this small number of events this may have affected the result. Not many a(prenominal) variables were included in this study, and researchers didnt mention how they controlled some possible confounders. Researchers were successful in identifying the advantages and limitations of the study. Results were properly presented in tables.Instead of expensive laminar air-flow system, installation of well-designed ventilation system is found beneficial. Scaltriti et.al (2007) conducted a study in Italy to examine effectiveness of well-designed ventilation system on air quality in operation theatre. They selected operation theatres of a newly built 300 beds comm unity hospital which have ventilation system designed to achieve 15 transact outdoor air changes per hour and are equipped with 0.3 m, 99.97% HEPA filters. All these satisfy the condition for a clean room as per ISO 7 standard. inactive samples of microbiological air counts were collected using Tripticase Soy Agar 90 mm plates left open thorough out the duration of the procedure. Active samples were also collected using a single state slit-type impactor. Total 82 microbiological samples were collected of which 69 were passive plates and 13 were active. Air dust was counted with a light-scattering particle analyser. Details of the surgery, number of people in the room, door initiation rate and estimated total use of the electrocautery unit were also collected.It was found that there were positive correlations between particle contamination, surgical technique (higher risk from general conventional surgery), electrocauterization and operation length. Door opening rate was found neg atively associated. Researchers suggest that this may because when theatre door open a turbulent air flow blows out of the operating room which may result decrease in the dust particles. No association was found between particle contamination and number of people present at the time of incision. Researchers suggest that human movement rather than human presence is the gene that determines airborne microbial contamination. It was found that average particle concentration in the theatres did not exceed the European ISO 14 644 standard limits for ISO 7 clean room, and so concluded that well-designed ventilation system is effective in control particulate contamination.Uncultivable or undiagnosable organisms can also be a reason for surgical site infections. It may be intemperate to identify such organisms through standard horti finale techniques (Tunney 1998). Clarke et.al (2004) conducted a quantitative study to examine the effectiveness of ultra-clean (vertical laminar flow) the atres in preventing infections by unidentifiable organisms. They used the molecular technique, Polymerase Chain Reaction (PCR), to detect bacteria presence. Their study compared the wound contamination during primary total hip replacement (THR) performed in standard and ultra clean operation theatres. 20 patients underwent primary THR from 1999 to 2001 were recruited for this study. Patients with forward incidents of joint surgery or infection were excluded. The standard operation theatres had 20 air changes per hour and CFU count was 50 CFU/m3, while ultra-modern theatres had 530 air changes per hour and CFU count was 3 CFU/m3.For all surgeries same infection control precautions were used. Two specimens each of pericapsular tissues were collected from posterior joint capsule both at the beginning and at the end of the surgery (total 80 samples). Patients were given antibiotic prophylaxis after taking the first specimen. All these samples were underwent Gram stain and culture to de tect bacterial colonies and Polymerase Chain Reaction (PCR) to detect bacterial DNA.Among the 20 specimens taken form the standard operation theatres at the beginning of the surgery only 3 were found positive with PCR, while from the ultra-clean theatres only 2 were found positive. None from both theatres found positive with culture. Samples from the standard theatres taken at the end of the surgery, 2 found positive by culture and 9 found positive by PCR. The contamination rate in the standard theatre at the end of the surgery found significantly greater than the beginning (p=0.04). Samples taken from the ultra-clean theatres, none was positive by culture while only 6 were positive by PCR. Statistical analysis found that contamination rate at the end of the surgery is not statistically different than the start (p=0.1). It was found that there were no statistically significant difference in overall contamination rate (p=0.3) between standard and ultra clean theatres. (I will add cri tique of this study here)NURSES ROLE IN INFECTION CONTROLUnderstanding the source of contamination in operating theatre and knowing the relationship between bacterial virulence, patient immune status and wound environment will suspensor in improving the infection rates (Byrne et al 2007).Nurses are responsible to take a proactive role in ensuring safety of their patients. To improve patient outcome, it is necessary for the nurses to take lead role in environmental control and identifying hazards through environmental surveillance (Neil 2005). Non-adherence to the principle of asepsis by surgical team is identified as a significant risk factor of infections. Hectic movement of surgical team members in the operating room and presence of one or more visitors were also found as major causes of SSI (Beldi G 2009). Nurses and managers should emphasise on controlling factors like the traffic in theatre, limiting the number of staff and reinforcement of exact aseptic technique (Allen 2010 ). Creedon (2005) argues that infections can reduce up to one tierce if staffs follow best practice principles. For better outcome staffs needs additional education and positive reinforcement.Nurses have a vital role in the development, reviewing and approving of patient care policies regarding infection control. Nurses are not only responsible for practicing the aseptic techniques but also responsible for monitoring other staff for their adherence to policies. They are responsible for developing training programmes for members of staff. Educating the environmental services personnel like technicians, cleaners will not only improve their knowledge in patient care but also provide a sense of commitment in patient outcomes (Neil 2005).Perioperative nurses can contribute in research regarding theatre ventilation system through organised data collection and documenting evidences. Nurses can contribute in big optimum and safe delivery of care in areas where environmental issues can put the patient at risk. Knowledge is changing fast, so it is important that staff must keep themselves up to date. Continues quality improvement is needed and it should be based on evidence based research and on-going appraisal of information (Hughes 2009).CONCLUSIONReviews of current research shows that still there is a lack consensus on the effectiveness of laminar airflow in infection control. Studies include in this review has used either clinical outcomes (infection or reoperation rate) or intermediate outcomes (particle count or bacterial count) to evaluate the effectiveness of laminar flow. Kakwani et.al (2007) found that re-operation rate was lower in laminar airflow theatres but Brandt et.al (2008) found SSI rate was high in hospitals with laminar flow. Clarke et.al (2004) found that contamination was not significantly different in ultra clean theatres compared to standard theatres equipped enhanced ventilation system. Supporting this finding Scaltriti et.al (2007) found well designed ventilation system is effective in reducing contamination.Study by Knobben et.al (2006) found that combination of systemic and behavioural changes are required to prevent intra-operative contamination. Miner et.al (2007) found that there were no significant differences in infection between hospitals that use laminar airflow and body exhaust suits.From these studies it can be concluded that use of laminar airflow alone can guarantee infection prevention. Behavioural and other systemic changes are necessary to enhance the benefits of laminar airflow. Evidence shows that conventional theatres equipped with enhanced ventilation system can prevent infection effectively, this can be consider as an alternative for expensive as laminar flow system.
